Title: Printer
Inventor: SAWA HIROSHI
IPC: B41J29/00
Filed: 1991-04-18
Abstract: PURPOSE:To evaluate print result automatically, improve efficiency of printing work, and detect failure earlier by comparing an image data read by an image read means with a printing data in a print buffer so as to evaluate print accuracy. CONSTITUTION:When a printing work is started in a state that a printing data to a receipt is stored in a print buffer, the printing data in the print buffer is printed on a receipt paper by a print head 20. The print result is read out immediately by an image sensor 25 and the read data is stored in a read buffer. When the printing by the print head 20 with respect to the whole print data in the print buffer is completed and the whole printed data are read out by the image sensor 25, the data in the print buffer is compared with the data in the read buffer. Thus, accuracy of printing on a sheet paper can be evaluated automatically and in real time.

Title: Command generating system of multi-axis servo system
Inventor: FUTAMI SHIGERU
IPC: G05B19/41
Filed: 1984-04-28
Abstract: PURPOSE:To reduce a working error by generating the position and speed commands of a main shaft by regarding time as their parameter, and generating the position and speed commands of a driven shaft by regarding the position of the main shaft as their parameter. CONSTITUTION:A positional function generator 7 erases the time parameter from position commands xr(t), yr(t) adopting time as its parameter, finds out a graph for command values of the driven shaft corresponding to the position of the main shaft and stores the graph by a proper means. A derivative generator 8 finds out a derivative dyr/dx corresponding to (x). As to the main shaft, dxr/dt is inputted on the basis of a command value xr(t) adopting time as its parameter at feedforward operation. The command for the driven shaft generates yr corresponding to the position (x) of the X axis from the graph of x-yr and inputs the yr to a position loop amplifier. In case of feedforward operation, dyr/dx corresponding to the position (x) of the X axis is generated from the graph of x-dyr/dx and a speed feedforward signal dyr/dt is obtained as the product of said signal and the speed dx/dt of the X axis and inputted to a speed loop amplifier.

IPC: H01L21/331
Filed: 1989-04-07
Abstract: PURPOSE:To prevent leakage from occurring between an emitter and a base and between the emitter and a collector by a method wherein between a first external base region having high concentration and an intrinsic base region, a second external base region having low concentration is formed. CONSTITUTION:By performing specific manufacture process, between a P<+> type diffusion layer 119 to be a first external base region having high concentration and a P<-> type diffusion layer 123 to be an intrinsic base region, a P type diffusion layer 122 to be a second external base region having low concentration is formed. Therefore the external base region having low concentration and an N<+> type diffusion layer 125 to be an emitter region having low concentration will not be in contact with each other. Thus good withstand voltage between the emitter and the base without leakage can be obtained. In addition the first external base region 119 and the intrinsic base region 123 are connected by the second external base region 122 thereby preventing increase in base resistance and leakage between the emitter and a collector from occurring.

Title: Production of nuclear fuel pellet
Inventor: YUDA RYOICHI
IPC: G21C3/62
Filed: 1990-04-03
Abstract: PURPOSE:To obtain the nuclear fuel pellet having >=50mum crystal grain size with good reproducibility while substantially preventing the coefft. of diffusion of the fission product gases in crystal grains from changing. CONSTITUTION:Silicate 5 of alumina silicate, etc., is placed on a sintering tray 4 consisting of Mo and the tray is inserted into an annular furnace 2 and is heated by a heating element 1 in steam flow. The alumina silicate having about 1600 deg.C eutectic point vigorously generates vapor at 1700 deg.C. On the other hand, uranium dioxide has the eutectic point at about 1700 deg.C with silica. These vapors, therefore, melt the crystal grain boundaries selectively and infilter the inside of pellets 3. A liquid phase is generated at the crystal grain boundaries by the infiltered silicate and the uranium dioxide and liquid phase sintering arise. The coarser grains of the crystal grain sizes are thereby formed. The similar effect is generated even if moldings are used in place of the sintered pellets. The silicate vapor and the additive of a metal oxide react to generate the material separate from the additive if a slight amt. of the additive is previously added into the moldings. The liquid phase is then generated at the crystal grain boundaries and the grains of the larger grain sizes by the liquid phase sintering are similarly obtd.
